The Annobón Paradise-flycatcher (Terpsiphone smithii) is a medium-sized passerine bird. It was previously classified with the Old World flycatcher family Muscicapidae, but the paradise-flycatchers, monarch flycatchers and Australasian fantails are now normally grouped with the drongos in the family Dicruridae, which has most of its members in Australasia and tropical southern Asia.

Some authorities, notably the African Bird Club treat Annobón Paradise-flycatcher as a subspecies of Red-bellied Paradise-flycatcher T. rufiventer smithii.
